Safety problem? Ethanol gasoline & fuel lines??
I recently had my 1975 450sl burn (total loss) due to what appears to have been leaking gas lines. I experienced this same leaking earlier in the month on my 1982 BMW R100RS and determined it to be, most likely, from the ethanol dissolving my OEM rubber hoses. NOT GOOD. I replaced the BMW hoses and carb parts, but it didn't dawn on me to replace the 450sl hoses.
Is this a problem we might all face with the changes in gasoline formulation, or could it be something else?? I guess I will buy another car, but I'd like to know so I don't make this same mistake more than 3 or 4 times !! Any thoughts? http://www.fuel-testers.com/ethanol_problems_damage.html |

The low percentage mixing of ethanol causes no corrosion issues that I have heard of. if you try the 85% version you need a flex fuel prepared system.

I would bet that the reason your lines leaked is not due to ethanol, but simply that they are more than 30 years old.

From your link:
Quote:
There is a simple test for ethanol in gasoline that the SCCA used to use (I don't know if they still do). In a graduated tube, introduce 10cc of your fuel and 10cc of pure ethylene glycol and shake. The ethylene glycol will absorb the ethanol from the fuel, growing the "green" part of the mix and shrinking the fuel. How much gets absorbed is the approximate ethanol content of your fuel. |
